Description:

Students will explore and map watershed data from a U.S. Forest Service GIS analysis titled “Forests, Water and People: Drinking water supply and forest lands in the Northeast and Midwest United States” (Barnes et Al, 2009.) The dataset students will explore, the “Ability to Produce Clean Water” or APCW, is an index that predicts how clean the water is in each watershed. APCW was created by a overlay or “sandwich” of six data layers: percent Forest Land, percent Agricultural Land, percent Riparian Forest Cover, Soil Erodibility, Road Density, and Housing Density.
